DRAFT-RIGGING FOR RAILWAY-CARS.

Speecaton of Letters Patent.

Application filed December 1, 1913. Serial No. 803,904.

full, clear, concise, and exact description,

reference being had to the accompanying drawings, forming a part of this specification. l i

My invention relates to improvements in draft rigging for railway cars.

The object of my invention is to provide a draft rigging having a comparatively easy initial action on forward movement of the draw bar.

In the drawings forming a part of thisY specification-Figure 1 is a plan view partly in horizontal section, one of the front stop members being shown in horizontal section on line 1--1 of Fig. 2, of a draft rigging embodying my invention; Fig. 2 is a side elevation of the front followerl and a vertical longitudinal section taken through one of the front stop members on line 2-2 of Fig. 1; Fig. 3 is a side elevation of the front follower and one of the front stop members; Fig. 4 is a cross section taken on line 1-41 of Fig. 2. A

Referring to the drawings the numerals 5, 5 represent draft sills or parts of the car frame to which the draft rigging is applied; G a draw bar having a draft yoke 7 suitably secured thereto; a draft gear 8 mounted i within the yoke, the said draft gear illustrated in the drawings comprising a shell 9 and compression resisting parts l() within the shell. f

The numeral 11 represents a front follower; 12, 12 rear stop members suitably secured to the draft members, preferably by the rivets 13, 13, and 14, 1a the front stop members. The front stop members are mounted between the draft sills, one on either sill, and are counterparts of each other. I therefore describe one of said stop members 14. It consists of a shell 15, preferably with two hollow spring chambers 30, 30 arranged one above the other, as illustrated in Fig. 2 of the drawings, each of said spring chambers being open at its rear end 16 and closed at its front end by the preferably integral plate 17, the forward end of the shell being provided with a flange 18, which is ypreferably integral with and forwardly extended from the inner wall 19 of the shell 15, the fiange 18 and the shell 15 being provided with suitable means, preferably the rivets 20, to rigidly secure the same to the adjacent draft member 5. In preferable construction the shell 15 is provided with the openings 21 alongl its inner face to permit the easy riveting of the same to the draft sill 5. A hollow casing 22, open at its forward end 23 and closed at its rear end by the preferably integral plate 24, is provided for each spring chamber. In each spring chamber a preferably helical spring 25 is mounted at the forward end against the wall! 17 of the shell 15, and at its rear end against the wall 21 of the casing 22. The wall 211 of the casing 22 is preferably provided with a shoulder 26 adapted to engage against the rear end of the shell 15, and limit the inward movement of the casing. The said casings of the front stop members are seated at their rear ends against the forward face 27 of the front follower 11.

In normal position of the parts of the draft rigging, as illustrated in Fig. 1 of the drawings, the hollow casings 22, 22 are rearwardly extended from the shell 15, and on forward movement of the draw bar the front follower moves the said casings forwardly, the forward movement thereof being resisted by the springs within the casings until the shoulders 26 engage the shells 15, whereupon the forward movement of the front follower determines, and the parts of the draft gear are brought into compression resisting action therewith. On rearward movement'of the draw bar the springs in the front stop members do not serve to resist the draw bars movement.

In preferable construction the plates 21 of the casings 22 on either stop member are joined by the connecting plate 31, there being a chamber 32 provided between the spring chambers in each stop member for the passage of a bolt 33 passing at its forward end through a flange 35 in the stop member, and provided with a nut 36 seated against said iiange, the said bolt at its rear end being provided with a head 37 .countersunk in the connecting plate 31, the bolt serving to limit the rearward movement of the casings 22, and to retain the said casings in their assembled relation with the shell 15.

I claim 1. In a draft rigging for railway cars, op-

ositel arranged sto members each com- P Y e y prising a shell having a plurality ofspring chambers arranged one above the other, and springs in each of said chambers.

2. In a draft rigging for railway ears, in combination, draft members, a pair of oppositely arranged stop members secured thereto, a spring chamber in each stop member, a spring for each chamber,a follower, -a draw bar and a draft gear connected to the draw bar, the springs being adapted to yield `to the pressure of the follower on forward movement of the draw bar before the draft gear is brought into compression resisting action.

3. In ,a draft rigging for railway cars, in combination, draft members, a pair of oppositely arranged stop members secured thereto, a spring chamber in each stop member, a spring for each chamber, a follower, a draw bar and a draft gear connected to the draw bar, the springs being adapted to yield to the pressure ofthe follower on forward movement of the draw bar, and until the follower abuts the stop members, before the draft gear is brought into compression resisting action.

l. In a draft rigging for railway cars, stop members, each comprising a rigid member, `a movable spring seat, a spring seated between the movable spring seat andthe rigid member, and a bolt between the rigid lmember and the movable spring seat to limit the expansion of the spring.

5. In ka draft rigging for railway ycar-s, stop members, each comprising a shell, a plurality of `spring chambers in the shell, a spring in each of said chambers, a movable spring seat for the outer ends of thesprings, and a bolt passing between the spring cli-ambers connecting the movable spring seat :to theshell'to limit the expanding movement of the springs.

6. In a draft rigging for railway cars, the combination with draft members adapted to receive shock absorbing mechanism and followers therebetween, of front and rear sets of stop members secured to lthe draft members, the stops of one of said sets beingeach provided with a ypreliminary compression spring which i-soperated prior to the operation ofthe shoclrabsorbing mechanism.
